The ZR36710 DVD decoder is targeted for third generation DVDproducts. The highly integrated ZR36710 is ideal for developinga high-quality DVD player. The product is based on Zoran'sstrong history in the DVD marketplace. Through the Standard-PlusTM design methodology, functions such as reverse trickplaysand zoom capability are provided. The ZR36710, through its Sil-iconSoftwareTM feature, has the capability to integrate keyfunctions such as 3D audio and Karaoke.

Highest Quality Audio

The internal architecture of the ZR36710, which is based onZoran's field proven audio DSP, enables the development of aDVD system which meets the highest quality audio standards.The ZR36710 DVD decoder includes an embedded 20-bit high-performance audio DSP which enables the Vaddis architectureto perform at audiophile quality for its audio output signals. Othersolutions, which use 16-bit audio technology cannot attain thisstatus. The high performance capability of the embedded audioDSP enables the implementation of additional audio processingalgorithms such as Karaoke and 3D audio.

At the heart of the Vaddis ZR36710 are two powerful processingunits: the Demux/Video Processor (DVP unit) and the AudioDecode Processor (ADP unit), a user programmable, 40 MIPS,DSP engine. The DVP unit operates from downloadable micro-code to parse the bitstream and route data to the appropriateunits. The Picture Reconstruction Unit completes the MPEG-2 orMPEG-1 video decode and passes the image to the Video PostProcessing (VPU unit). The VPU unit performs vertical/horizon-tal scaling, decodes and blends Sub-picture data, inserts Line 21(close caption) text and overlays On Screen Display data.

KEY FEATURES

DTS and MPEG Multi-channel Passthrough

The ZR36710 incorporates the capability to provide a digitaloutput of DTS or MPEG 5.1 through the S/PDIF output. Thisdigital data is transmitted for use by an audio receiver for multi-channel decoding.

Karaoke

Karaoke is a popular feature for the Asia market. Karaokefeatures can be implemented in the ZR36710, thus eliminatingthe need for an external karaoke processor. Voice Canceling isa feature to eliminate the singer's voice on a CD by comparingleft and right channels and filtering out the vocal content,allowing you to sing along. The echo function provides the effectof singing in a large auditorium and slightly modifies the singer'svoice to enhance the sound. Key Control adjusts the pitch of themusic by quarter tones to allow the pitch of the music to beshifted to match the pitch of the singer's voice.

Reverse Trickplay

Further adding to the video capability of the Vaddis, theZR36710 incorporates reverse trickplay functionality to provideseamless reverse functions in addition to the standard trickplay

functions common to DVD players. The reverse trickplayprovides smooth transitions for a viewer to single step or fastreverse through scenes.

Patented SDRAM Memory Usage

The ZR36710 uses a patented and proprietary implementationfor DVD decoding with a single 16 Mbit SDRAM. This dramati-cally reduces the number of the chips and the size of therequired memory, thereby lowering the power consumption andthe overall cost of a DVD system.

A Solution for the Consumer DVD Player Market.

The Vaddis III ZR36710 can be used in a DVD Player design.High quality audio is a key feature of DVD and the Vaddissupports the highest quality Dolby Digital possible for a DVDplayer design. In addition, the functions of reverse trickplay andzoom capability enhance the video playback. Support for DTSpassthrough enables the playback of video titles that areencoded with DTS audio tracks. Support for MPEG5.1 providesthe same capability. In summary, the ZR36710 is ideally suitedfor developing a high quality, feature rich third generation DVDplayer design.
